This paper aims to identify and systemize the research streams in regional cluster upgrading. Cluster upgrading belongs to broader research in the dynamics of industrial agglomerations, currently, the major topic in studies on clusters. Within this literature, the upgrading concept differentiates by the focus on structural change in response to the insertion of regional clusters into global value chains (GVCs). Based on the narrative literature review, we identify and discuss two major research streams and classify them as the positive and the normative. Moreover, we elaborate a framework for studying the antecedents of cluster upgrading to conclude with research questions that may serve further systematic reviews and empirical investigations. This paper provides two contributions to the cluster dynamics literature with a focus on the upgrading of industrial agglomerations. First, it offers a comprehensive approach to the cluster upgrading theory by integrating the fragmented research in this area. Second, it proposes a theoretical framework to set up further research directions.

集群升级中的研究流。文献综述

本文旨在识别和系统化区域集群升级中的研究流。集群升级属于产业集聚动力学的更广泛研究，是当前集群研究的主要主题。在此文献中，升级概念的区别在于对结构变化的关注，以响应将区域集群插入全球价值链（GVC）。在叙述性文献综述的基础上，我们确定并讨论了两个主要的研究流，并将其分为正面研究和规范研究。此外，我们精心设计了一个框架，用于研究集群升级的前因，以得出可以为进一步的系统综述和实证研究服务的研究问题作为结论。本文为集群动力学文献提供了两个贡献，重点是产业集聚的升级。首先，它通过整合该领域的零散研究为集群升级理论提供了一种全面的方法。其次，提出了建立进一步研究方向的理论框架。
